What is thixotropic ink, and why is it important?

Thixotropic ink is a special type of ink that does not flow freely at rest but liquefies when in motion—in this case, when writing. Inside the cartridge, it is hermetically sealed in a pressurized reservoir. An internal separator keeps it separate from the pressurized nitrogen, ensuring a constant and controlled flow while writing, without spilling or drying out.
